It is hard to find an inventive and innovative slots online for Canadians, nowadays. It seems that every theme has already been covered and every slots variation has been introduced. Therefore, when I first came across Castle Builder™ online slots, I was in for a very pleasant surprise. Microgaming has come up with a truly ingenious slots game that incorporates an engaging storyline, a slots game and a building project in one truly legendary slots game. In fact, I will go so far as to say that this may be one of the top online Canadian casino games that I have played to date.


Castle Builder takes us straight into the Medieval world and tells the story of a Medieval King marrying off his daughters and building castles for them to live in, and extending his kingdom in the process. As the player, your will pick out the suitable bridegrooms for the daughters and acquire all of the building materials necessary for constructing the castles.

The actual 5 reel and 15 payline slots game takes up only half of your screen as the rest of the screen depicts the construction site where the castle is being built.

You can successfully build the castles by collecting the building symbols on the reels. The building materials come in standard, bronze, gold and silver variations. Two, three, four or five of the building symbols on a payline will add a symbol to your building material collection and get you closer to the completion of your project.

As well as the building symbols, the other symbols in the game include royal King, Queens, Prince and Princesses with the K, Q, J and 10 icons attached to them. There are also bags of coins, treasure chests, vault doors and the old builder symbol.

The coin range for the Castle Builder slots ranges from 0.05 to 1.00. You can choose to activate all 15 lines or only a number of lines, the more lines you activate, the more chances you have of winning the largest payouts.

The top payout is 20,000 coins. This payout is awarded for either five of the old builder symbols or five of the vault door symbols on an activated payline. The game has a RTP of 96.5%.


Castle Builder™ online slots has 5 reels and 15 paylines. To begin building castles, you need at least two building material symbols on every activated payline. Two of the building materials symbols will result in a standard block. If you land three building material symbols will receive a bronze block. When you hit four of the building material symbols you will be awarded a silver block, and, lucky players who hit five building material symbols will be awarded with a golden block.

As soon as you begin to collect building materials, you can begin to build castles. The more valuable your blocks are the higher value your completed castle will have. When your castle is complete, you will be taken to another screen. The second screen features a princesses is attempting to pick between three handsome bridegrooms. Each suitor has a different value that is concealed from the player.  You will be entrusted with picking the suitor for the princess. Once you have picked the suitor, his value will be exposed.

Once the happy couple have moved into their home, the game continues.  You will move on to begin building the next castle and hope marry off the next daughter in line. As you progress in the game, check your progress by simply clicking on the map and see how you have helped the King increase his Kingdom.

There are four levels that must be climbed before you can make your way to the end of the game, these levels are Empire, Forana, Ethril and Ilrain. As you climb up the levels you will also metamorphosis from a simple worker to a rich builder surrounded by gold and silver. After every completed level, and before you progress to the next level, you will once again need to help pick out a suitable suitor for one of the princesses.

The old builder symbol is the wild symbol and it will substitute for all of the other symbols to help you create winning combinations.
